Abstract
An asynchronous data transmission method and a telecommunication system for transmitting asynchronous data characters and status information of a terminal interface and possibly other control and synchronization information through a synchronous traffic channel or a set of synchronous traffic channels. The system has an arrangement including a transmission protocol utilizing an asynchronous-to-synchronous conversion. The transmission protocol has protocol data units for transmission over the traffic channel or set of traffic channels. Each protocol data unit contains a predetermined number of terminal interface asynchronous data characters without start and stop bits, and the terminal interface status information and possibly other control or synchronization information, concatenated between a common start bit and a common stop bit.
